Description

本発明は、往復動式モータに関し、特に、動作時に発生する偏心運動に基づく摩擦を防止してその性能を向上させることができる往復動式モータに関する。   The present invention relates to a reciprocating motor, and more particularly to a reciprocating motor capable of improving its performance by preventing friction based on eccentric motion that occurs during operation.

往復動式モータは、立体状のフラックス（磁束）を有する一般のモータとは異なって、平面状のフラックスを有し、フラックスの変化によって外側固定子と内側固定子との間に介在するマグネット可動子が線状に動く。   The reciprocating motor is different from a general motor having a three-dimensional flux (magnetic flux), and has a planar flux, and the movable magnet is interposed between the outer stator and the inner stator by changing the flux. The child moves linearly.

図１及び図２に示すように、従来の往復動式モータは、内部にコイル５０を巻回するボビン６０の外側に複数のシート１２が放射状に積層されて円筒状をなす外側固定子１０と、外側固定子１０の内周と所定の空隙を維持するように配置され、複数のシート２２が放射状に積層されて円筒状をなす内側固定子２０と、外側固定子１０と内側固定子２０との間に配置され、複数のマグネット３０が周方向に設置されて円筒状をなすマグネット可動子４０とを含む。   As shown in FIGS. 1 and 2, the conventional reciprocating motor includes a cylindrical outer stator 10 in which a plurality of sheets 12 are radially stacked on a bobbin 60 around which a coil 50 is wound. The inner stator 20 is arranged so as to maintain a predetermined gap with the inner periphery of the outer stator 10, and a plurality of sheets 22 are radially stacked to form a cylindrical shape, and the outer stator 10 and the inner stator 20 And a magnet mover 40 having a plurality of magnets 30 arranged in the circumferential direction and having a cylindrical shape.

ボビン６０の一側には、ボビン６０内のコイル５０に外部電源を印加するためのターミナル７０が突出形成され、ターミナル７０を挟んでその左側及び右側には、複数のシート１２が均一に積層される。   On one side of the bobbin 60, a terminal 70 for applying an external power source to the coil 50 in the bobbin 60 is projected and formed, and a plurality of sheets 12 are uniformly laminated on the left and right sides of the terminal 70. The

以下、このように構成される従来の往復動式モータの動作について説明する。即ち、外側固定子１０のコイル５０に電源が供給されると、コイル５０の周りにフラックスが形成され、そのフラックスは、外側固定子１０および内側固定子２０を通して閉ループを形成するように生成される。これによって、マグネット可動子４０がフラックスの方向によって押されるか又は引っ張られることによって直線的往復運動を行う。   Hereinafter, the operation of the conventional reciprocating motor configured as described above will be described. That is, when power is supplied to the coil 50 of the outer stator 10, a flux is formed around the coil 50, and the flux is generated so as to form a closed loop through the outer stator 10 and the inner stator 20. . Thereby, the magnet movable element 40 is linearly reciprocated by being pushed or pulled depending on the direction of the flux.

このような従来の往復動式モータでは、外側固定子１０のラミネーションシート１２間に外部電源をコイル５０に接続するターミナル７０が設置されるため、ターミナル７０の幅に該当する部分はラミネーションシート１２が積層されない。このため、ターミナル７０の近くで発生する電磁気力は、ターミナル７０の対向側で発生する電磁気力に比べて相対的に小さくなる。   In such a conventional reciprocating motor, since a terminal 70 for connecting an external power source to the coil 50 is installed between the lamination sheets 12 of the outer stator 10, the portion corresponding to the width of the terminal 70 is the lamination sheet 12. Not stacked. For this reason, the electromagnetic force generated near the terminal 70 is relatively smaller than the electromagnetic force generated on the opposite side of the terminal 70.

したがって、外側固定子１０と内側固定子２０との間で形成される電磁界が均一にならず、ターミナル７０の対向側へ向かって電磁界が偏心的に形成される。   Therefore, the electromagnetic field formed between the outer stator 10 and the inner stator 20 is not uniform, and the electromagnetic field is formed eccentrically toward the opposite side of the terminal 70.

このような電磁界の偏心現象により、マグネット可動子４０がターミナル７０の設置部位の対向側、即ち、図３及び図４に示す矢印方向に移動するため、円筒状のマグネット可動子４０が外側固定子１０と衝突して、マグネット可動子４０の偏心運動による摩擦を生ずる。   Due to such an electromagnetic field eccentricity phenomenon, the magnet mover 40 moves in the direction opposite to the installation site of the terminal 70, that is, in the direction of the arrow shown in FIGS. Colliding with the child 10 causes friction due to the eccentric movement of the magnet mover 40.

本発明は、外側固定子と内側固定子との間に形成される電磁界を均一にして、外側固定子と内側固定子との間で往復する円筒状のマグネット可動子の偏心運動によって摩擦が生ずるのを防止することができる往復動式モータを提供することを目的とする。   In the present invention, the electromagnetic field formed between the outer stator and the inner stator is made uniform, and friction is caused by the eccentric motion of the cylindrical magnet mover that reciprocates between the outer stator and the inner stator. It is an object of the present invention to provide a reciprocating motor that can be prevented from occurring.

このような目的を達成するために、本発明に係る往復動式モータは、内部にコイルが巻回されるボビンの外側に複数のシートが放射状に積層されて円筒状をなす外側固定子と、前記外側固定子の内周面から所定の空隙を維持するように該外側固定子内に配置され、複数のシートが放射状に積層されて円筒状をなす内側固定子と、前記外側固定子と前記内側固定子との間に配置され、複数のマグネットが周方向に設置されるマグネット可動子と、前記外側固定子の一側に設けられてコイルに外部電源を接続するターミナル部と、前記外側固定子の周方向において前記ターミナル部を基準にして等間隔で該外側固定子に設けられ、シートが積層されない磁力バランス部とを含む。   In order to achieve such an object, a reciprocating motor according to the present invention includes a cylindrical outer stator in which a plurality of sheets are radially stacked on the outside of a bobbin around which a coil is wound, An inner stator disposed in the outer stator so as to maintain a predetermined gap from the inner peripheral surface of the outer stator, and a plurality of sheets are radially stacked to form a cylindrical shape, the outer stator, and the A magnet movable element arranged between the inner stator and a plurality of magnets arranged in the circumferential direction, a terminal part provided on one side of the outer stator to connect an external power source to the coil, and the outer fixed And a magnetic force balance portion that is provided on the outer stator at equal intervals with respect to the terminal portion in the circumferential direction of the child and on which the sheets are not stacked.

本発明の前述の、および他の目的、特徴、態様および利点は、添付図面を参照しての、本発明の以下の詳細な説明から明らかにされる。   The foregoing and other objects, features, aspects and advantages of the invention will become apparent from the following detailed description of the invention when taken in conjunction with the accompanying drawings.

以下、添付の図面を参照して、本発明に係る往復動式モータの好ましい実施形態について説明する。   Hereinafter, preferred embodiments of a reciprocating motor according to the present invention will be described with reference to the accompanying drawings.

図５及び図６に示すように、本発明の第１実施形態に係る往復動式モータは、内部にコイルが巻回されるボビン１６０の外側に複数のシート１１２が放射状に積層されて円筒状をなす外側固定子１１０と、外側固定子１１０内に配置され、複数のシート１２２が放射状に積層されて円筒状をなす内側固定子１２０と、外側固定子１１０と内側固定子１２０との間に配置され、複数のマグネット１３０が周方向に設置される円筒状のマグネット可動子１４０とを含む。   As shown in FIGS. 5 and 6, the reciprocating motor according to the first embodiment of the present invention has a cylindrical shape in which a plurality of sheets 112 are radially stacked on the outside of a bobbin 160 around which a coil is wound. Between the outer stator 110 and the inner stator 120. The outer stator 110, the inner stator 120 disposed in the outer stator 110, and a plurality of sheets 122 are radially stacked to form a cylindrical shape. And a cylindrical magnet mover 140 that is disposed and in which a plurality of magnets 130 are installed in the circumferential direction.

ボビン１６０の一側には、ボビン１６０の内部に巻回されるコイルと外部電源とを接続させるターミナル１７０が突出形成され、ターミナル１７０を挟んでその左側及び右側には、複数のシート１１２が均一に積層される。   On one side of the bobbin 160, a terminal 170 for connecting a coil wound inside the bobbin 160 and an external power source is formed to protrude, and a plurality of sheets 112 are uniformly formed on the left and right sides of the terminal 170. Is laminated.

また、ターミナル１７０が設置される付近と該ターミナル１７０の対向側との間で生成される電磁界のアンバランス現象を防止できるように、該ターミナル１７０の対向側、即ち、外側固定子１１０の周方向において該ターミナル１７０を基準にして該ターミナル１７０から１８０°の間隔を有する部位には、ラミネーションシート１１２が積層されない磁力バランス部８０が設置される。   Further, in order to prevent an unbalance phenomenon of the electromagnetic field generated between the vicinity where the terminal 170 is installed and the opposite side of the terminal 170, the peripheral side of the outer stator 110 is opposed to the opposite side of the terminal 170. A magnetic force balance unit 80 on which the lamination sheet 112 is not laminated is installed at a part having a 180 ° interval from the terminal 170 in the direction.

一方、図７及び図８に示すように、本発明に係る往復動式モータの第２及び第３実施形態においては、ラミネーションシート１１２が積層されない磁力バランス部１８０、２８０は、ターミナル１７０を基準にして外側固定子１１０の周方向にそれぞれ互に１２０°及び９０°の間隔をおいて形成される。また、これより狭い間隔で複数の磁力バランス部を形成することもでき、その間隔は往復動式モータの性能によって適宜調節することが好ましい。   On the other hand, as shown in FIGS. 7 and 8, in the second and third embodiments of the reciprocating motor according to the present invention, the magnetic force balance portions 180 and 280 where the lamination sheet 112 is not stacked are based on the terminal 170. The outer stator 110 is formed at intervals of 120 ° and 90 ° in the circumferential direction. In addition, a plurality of magnetic force balance portions can be formed at narrower intervals than this, and the intervals are preferably adjusted as appropriate according to the performance of the reciprocating motor.

ここで、磁力バランス部８０、１８０および２８０は、ターミナル１７０と同一形状又は同一断面積を有するように形成することが好ましい。また磁力バランス部８０、１８０および２８０は、それぞれ互に等間隔で形成され、かつボビン１６０と一体に形成されるのが好ましい。   Here, the magnetic force balance portions 80, 180, and 280 are preferably formed to have the same shape or the same cross-sectional area as the terminal 170. The magnetic force balance portions 80, 180, and 280 are preferably formed at equal intervals from each other and formed integrally with the bobbin 160.

以下、このように構成される本発明に係る往復動式モータの動作及び効果について説明する。   Hereinafter, the operation and effect of the reciprocating motor according to the present invention configured as described above will be described.

先ず外部電源が印加され、コイルに電流が流れると、コイルの周りにフラックスが形成され、そのフラックスは、外側固定子１１０と内側固定子１２０に沿って流れて閉ループを形成する。   First, when an external power supply is applied and a current flows through the coil, a flux is formed around the coil, and the flux flows along the outer stator 110 and the inner stator 120 to form a closed loop.

外側固定子１１０と内側固定子１２０で形成されるフラックスと、マグネット１３０で形成されるフラックスとの相互作用により、マグネット可動子１４０が軸方向の力を受け、外側固定子１１０と内側固定子１２０との間で直線状に動く。そして、コイルに流れる電流の方向が変化すると、外側固定子１１０と内側固定子１２０とで形成されるフラックスの方向も変化して、円筒状のマグネット可動子１４０が逆方向に動く。   Due to the interaction between the flux formed by the outer stator 110 and the inner stator 120 and the flux formed by the magnet 130, the magnet mover 140 receives an axial force, and the outer stator 110 and the inner stator 120. It moves in a straight line between. When the direction of the current flowing through the coil changes, the direction of the flux formed by the outer stator 110 and the inner stator 120 also changes, and the cylindrical magnet mover 140 moves in the opposite direction.

ここで、ラミネーションシートが積層されないターミナル１７０と磁力バランス部８０、１８０および２８０が互に等間隔で配置されるため、外側固定子１１０と内側固定子１２０との間で生成される磁界が均一に形成される。   Here, since the terminal 170 on which the lamination sheet is not laminated and the magnetic force balance portions 80, 180, and 280 are arranged at equal intervals, the magnetic field generated between the outer stator 110 and the inner stator 120 is uniform. It is formed.

従って、外側固定子１１０と内側固定子１２０との間で直線往復運動を行う円筒状のマグネット可動子１４０は、偏心することなく同一軸線上で持続的に往復運動を行うことになる。   Therefore, the cylindrical magnet movable element 140 that performs linear reciprocation between the outer stator 110 and the inner stator 120 continuously reciprocates on the same axis without being eccentric.

本発明に係る往復動式モータは、ラミネーションシートが積層されないターミナルと磁力バランス部とが互に等間隔に形成されることによって、外側固定子と内側固定子との間で往復する円筒状のマグネット可動子の偏心運動による摩擦を防止して往復動式モータの性能を向上させることができる。   A reciprocating motor according to the present invention is a cylindrical magnet that reciprocates between an outer stator and an inner stator by forming a terminal on which a lamination sheet is not stacked and a magnetic force balance portion at equal intervals. Friction due to the eccentric movement of the mover can be prevented and the performance of the reciprocating motor can be improved.

本発明の思想および範囲から離れることなく、本発明においていくつかの修正および変更をなしうることは、当業者にとって自明なことである。したがって本発明は、特許請求の範囲内でもたらされる本発明の修正および変更をも含むものである。   It will be apparent to those skilled in the art that several modifications and variations can be made in the present invention without departing from the spirit and scope of the invention.
